2.2. Challenges in Understanding Manuals

And also, you know, don’t have too many offsets you know here, this is like too many, so symmetrical but still it’s too many offsets in it but then either try to make more of a defined shape because that is where you can even have a diagonal bracings, you can have some kind of support system so, it will; it is at least bound to a; this plan should be square or rectangular, if it is rectangular then you need to have a kind of intermediate support systems into it.

This section discusses the importance of structural planning in building designs. It highlights that having too many offsets in a building can weaken its stability. Ideal designs should be more defined, such as square or rectangular shapes, which can incorporate diagonal bracings and support systems. These design choices help maintain structural integrity, especially in the face of external forces like wind or earthquakes.

Think of a bookshelf. If the shelves are unevenly spaced and not secured properly, they might collapse under the weight of the books. Conversely, a sturdy bookshelf with evenly spaced shelving and diagonal supports can hold much more weight safely. This is similar to how buildings need well-structured designs to support themselves.

Now, asymmetric buildings with empty pockets are more vulnerable to damage because don’t leave these empty pockets, we tried to fill that and that is where these are more stable you know, the symmetric buildings are more stable and also when we say about the row house planning; the row house planning also creates wind tunnel effects because the moment your house is one step to another, next to the shore and then it channels the wind and that is where it can damage the edges of the walls or the corners.

This segment explains how asymmetric buildings are at a higher risk of damage, particularly if they have empty pockets or openings. Filling these gaps makes the structure more stable. The text also introduces row house planning and its drawbacks, like creating wind tunnel effects where strong winds are channeled between closely spaced houses, leading to potential damage at the corners and edges.

Picture a row of open umbrellas on a windy day. If they’re set too close together, the wind funnels between them, causing them to flip and break. In contrast, if they are spaced out, each can maintain its position more effectively. Just like spacing out umbrellas, buildings need careful design to manage wind flow without causing damage.

In fact, if you ever visit in the coastal villages of Tamil Nadu and the coastal areas; most of the times your short phase is of the building is facing the wind direction and whereas, in horizontal phase because that is where they have less number of openings and either that, if they are facing that side and they will have less number of openings and otherwise, if they mostly they orient so, the whole building pattern is like you have the seashore and you have these.

This part discusses how buildings are oriented in coastal areas of Tamil Nadu. It emphasizes that the shorter side of houses often faces the wind, with fewer openings to protect against wind-related damage. This orientation is a strategic choice based on geographic conditions, helping to safeguard the structures from the forces of nature.

Imagine a sailboat that turns its bow into the waves; it is much more stable than one that faces sideways to the waves. Similarly, houses designed with the wind in mind are like boats facing the waves, reducing the chance of damage during storms.

So, when we say about do not use cement and sand to be less than 1.6 okay, 1:6, so for 1 cement and 6 part of the sand. So, you should not make use of the combination of this mortar not less than 1:6, either it is recommended to use 1 sand, 1 cement and 6 sand or 1 lime with 3 sand or 1 cement, 3 lime and 9 sand, so this is a kind of mortar mixes which normally guidelines do recommend and at the end of the day, all these are coming from the proper IS code but these are only a thumb rules.

The text emphasizes the importance of maintaining quality in construction materials and proportions. It advises against using cement and sand mixtures with a ratio lower than 1:6, outlining preferred ratios for mortar mixes. Understanding these guidelines, which are based on established standards, is key to ensuring the structural integrity and longevity of buildings.

Consider baking a cake; if you don’t measure the flour, sugar, and eggs correctly, the cake won’t rise or taste right. Similarly, using the right ratio of construction materials is essential for a building to stand strong and safe.

And many of these manuals, when they are published in English, it becomes very hard how a local mason can understand it, so that is where a recent efforts have been done by architect Benny Kuriakose after the recent Kerala floods. So, what he did was he developed a manual for retrofitting and flood resilient design for flood-affected areas in Kerala. So, the Malayalam version is already printed and the English version is on the process.

This part highlights a significant challenge in manual comprehension for local masons due to language barriers. English manuals can be difficult for local workers to understand. Architect Benny Kuriakose recognized this issue and created a more accessible manual in Malayalam for flood-resilient designs, supporting local builders with practical solutions.

Think of trying to follow a recipe written in a language you don’t speak; it can be confusing and lead to mistakes. By translating these manuals into local languages, like Malayalam, it's like providing a recipe in a language familiar to the cook, ensuring better understanding and application.

But still, I could show you some images of what his work and it was very diagrammatic and really illustrative work. He looks into the before coming into the solutions, he actually explains the situation of how the causes you know, this is a very important aspect of developing any guidance, so one has to understand the consequences of these disasters and especially, what are the causes; root causes for it.

This segment stresses the need to comprehend the causes of disasters before proposing solutions. Architect Kuriakose's work includes illustrative diagrams that demonstrate disasters' effects and root causes. Understanding these elements is crucial for developing effective guidelines for future safety.

If you have a recurring problem of flooding in your house, you wouldn't just fix it without understanding why it floods each time. You'd analyze the causes, like clogged drains or poor drainage design, before implementing a long-term solution. In the same way, understanding disaster causes is key to creating effective preventive measures.
